PAS-Läufer-Hilfsmatt ab dem 4. Zug.
Die letzten 14 Züge sind identisch mit Kardos, P0502947.
Außerdem Selbstplagiat, V. M. veröffentlichte diese Aufgabe bereits 2008 in Schachmatnaja Komposizija (ganz leicht modifiziert, siehe P1080117).
Die Angabe "harmonie 2009" ist unsicher, denn sie wurde dem Hopper Magazine 03 (Zweitquelle) entnommen.
